However, whether their self‐concept structurally differs—specifically in its uniqueness versus its sociality—remains empirically unclear.\n\n\nMethod\nTwo experimental studies were conducted. Study 1 (n = 62 mothers) employed a classical self‐reference task to assess self‐concept uniqueness. Study 2 (n = 56 mothers) utilized a Remember/Know paradigm to examine the relational integration of their children into the self‐concept of mothers. Participants consisted of mothers of preschool‐aged children, divided into two groups: those with typically developing (TD) children and those with children diagnosed with developmental delays.\n\n\nResults\nBoth groups demonstrated a strong and equivalent self‐referential effect, indicating preserved self‐concept uniqueness among mothers of CSN. Only mothers of CSN showed comparable memory enhancement for child‐related and self‐related information, reflecting a distinct integration of the child into the maternal self‐concept—a pattern not observed among mothers of TD children.\n\n\nConclusion\nMothers of CSN maintain an individual self‐concept while also exhibiting a relational self‐structure in which the child is cognitively incorporated as part of the self.\n\n\nImplications\nFindings contribute to self‐expansion theory and provide evidence for integrated self‐other representation in maternal identity. Results also suggest that under high caregiving demands, self‐expansion can occur without diminishing self‐distinctiveness—a pattern that may inform how maternal self‐concept is structured in similar high‐caregiving contexts.\n\n"]
